20100038865 | Metal cylinder head gasket without a spacing layer - The invention relates to a metal cylinder head gasket provided with at least one opening corresponding to a combustion chamber of an internal combustion engine, comprising a function layer and an annular support arranged thereon. The functional layer comprises one full bead. The cylinder head gasket is characterised in that the annular support comprises one full bead which is defined on the functional layer, and the annular support comprises one bead which is arranged on the side of the full bead which is oriented away from the combustion chamber The invention also relates to a metal cylinder head gasket provided with at least one opening corresponding to a combustion chamber of an internal combustion engine, comprising an upper functional layer, an annular support and a lower functional layer. The annular support is arranged between the upper functional layer and the lower functional layer and is adjacent to the lower functional layer. The upper functional layer comprises one full bead which is adjacent to the annular support. The cylinder head gasket is characterised in that the lower functional layer comprises one bead which is arranged on the side of the full bead which is oriented away from the combustion chamber. | 02-18-2010 |
20100109257 | METHOD FOR THE PRODUCTION OF FLAT SEALS, AND FLAT SEAL - Disclosed is a method for mechanically connecting flat seals comprising at least two layers. In said method, the individual layers are placed in the area of a tool, at least one punch that has an approximately circular cross-section partially cuts the layers at defined points of the respective connection zone, and at least some of the remaining material is deformed outside the respective cut zone to form bent zones such that the respective cut zone is round and the respective bent zone is straight. Burrs of at least one of the layers are effectively connected to the material of at least one other layer in order to form a removable clamping connection, said burrs being formed in the cut zone. | 05-06-2010 |
20100301567 | WELDED METAL SEAL - The invention discloses a metal seal with a seam, wherein the metal seal has at least one sealing regions which is delimited on two sides by a respective boundary in order to be in seal-forming contact with at least one corresponding sealing surface, wherein the seam is provided with at least one weld seam, which is characterized in that each weld seam extends only outside the boundaries of at least one sealing region, such that he metal seal at eh seam between the boundaries of at least one sealing region is unwelded over the entire thickness of the seam. | 12-02-2010 |
20120056386 | MULTILAYER SEALING RING - A sealing ring for components of an internal combustion engine, with a first and a second axial sealing zone, includes an inner closed ring with a V-shaped cross-section, and an outer closed ring with a V-shaped cross-section. The open side of the outer closed ring points in the same direction as that of the inner ring. | 03-08-2012 |
20120098210 | FLAT SEAL HAVING A SOLID BEAD - A metallic flat gasket with a solid bead has at least one metallic layer ( | 04-26-2012 |
20120126491 | FLAT SEAL COMPRISING SEALING BEAD AND EMBOSSING, AND METHOD FOR THE PRODUCTION THEREOF - A metallic flat seal, in particular a cylinder head gasket, includes at least one through-hole, a functional layer, a spacer layer, and a stopper layer which is arranged between the functional layer and the spacer layer, as well as a closed sealing bead around every through-hole in the functional layer, wherein the sealing bead points in the direction of the stopper layer, the seal additionally comprising an embossed closed contour around every through-hole in that least the stopper layer, the functional layer or the spacer layer, wherein the contour forms a fixing aid. A method is also provided for making such a gasket. | 05-24-2012 |
20120228835 | METAL CYLINDER HEAD GASKET WITHOUT A SPACING LAYER - One aspect of the invention relates to a cylinder head gasket provided with at least one opening corresponding to a combustion chamber of an internal combustion engine. The gasket has a function layer with a full bead and an annular support with a bead. The bead of the annular support is arranged on the side of the full bead which is oriented away from the combustion chamber. Another aspect of the invention relates to a cylinder head gasket having an upper functional layer, an annular support and a lower functional layer. The annular support is arranged between the upper and lower functional layers and is adjacent to the lower functional layer. The upper functional layer comprises one full bead, and the lower functional layer has a bead arranged on the side of the full bead which is oriented away from the combustion chamber. | 09-13-2012 |
20140020650 | COMPOSITE MATERIAL HAVING STAMPING AND MICRO-PERFORATION - A method includes the steps of providing a first panel of aluminium material; providing a second panel of steel material; stamping a plurality of first pimple-like bulges in the first panel; stamping a plurality of second pimple-like bulges in the second panel, wherein the arrangement of the second pimple-like bulges is congruent with the arrangement of the first pimple-like bulges; bringing together the sides of the first and second panels that are furnished with the bulges, so that the domes of each set of pimple-like bulges lie opposite each other; and clipping the first and second panels together to form a composite by ensuring that at least one tongue is broken out of each of the pimple-like bulges on the second panel and pressed into the corresponding pimple-like bulges in the first panel. | 01-23-2014 |
